COLLAPSIBLE PACKING CASE.

Application filed August 30, 1923.

The present invention relates to a collapsible packing case of verygreat rigidity when assembled for use and which will occupy a reducedspace when dismantled for transit when empty. This result is obtained bya special system of folding allowing the different elements forming thesides and bot-,

tom of the pa king case to be arranged one inside the other protected bythe edges of the top and bottom being bent up at right angles. Theseedges which form rigid welded dihedral also serve to strengthen thelateral sides of the case at the level of the top and bottom and givethem a greatly increased strength.

These cases may be made either with solid sides cut out or joined orwith hoops reinforced by corners to form a frame having solid oropenwork sides for the transport of live poultry or other goods.

The accompanying drawing shows one form of the invention.

Fig. 3 perspective view on a smaller scale showing the different partsbefore assembly.

Figs. l and 5 are detailed views in section and elevation respectivelyof the method of utilizing togethe the lateral sides.

According to the invention the sections forming the bottom a and the lid6 have heir edges a, a a a 00', a b bent round at right angles either bypressing or by being cut out and raised in a bending machine and weldedto form the dihedral angles a, a a a a a, etc, in such a way as toobtain a rigid frame standing out a few centimetres all round the bottomand top formed by the sections a and b.

Two of the sides 0, (Z of the packing case are pivoted to the bottom aby hinges c c (Z (Z arranged in the space formed between the bottom andthe frame a a When closed these sides 0, (Z, lie against the bottom a 3)whilst when the case is in position they are pivoted through 90 on theirrespective hinges and come into place against the frame a a which limitstheir movement and serves to support them.

The other two sides 6, f are formed in the same way by two sectionshaving edges 6 e e and f f f bent at right angles by pressing or bybeing cut out and welded at Serial No. 660,218.

the junction points in such a way as to form a continuous band roundthree sides. The fourth side a f, is cut out to form inclines c e c andf f f corresponding respectively as to position and size to the plainlateral edges a a, a a, a, d of the bot tom a.

l I hen the case is dismantled (Fig. 2) the sides a and 7 fit into theinterior of the skeleton frame formed by the bottom a and the raisededges. Vlhen assembled for use the plain sections 6*, are held againstthe inclines of the same size between the parts a a, a a a a in such away as to'form a type of pinless dismountable hinge, then the sides 6and 7 being turned through 90 are prevented from turning further by theedges a a, a, a a, a which serve to support them.

\Vhen the four lateral sections 6, 0, (Z, c are raised (Fi 1) they areheld in this position by rivets having enlarged heads, 9, h, i, jarranged to turn in the sections a and f and which after being engagedin the slots 70, Z, m, n, in the sections 0 and d are turned through 90Figs. 4 and 5).

The lid Z) may comprise a door 6 carried on hinges b 6 to allow thepoultry or other merchandise to be inserted. When it is employed on thesides of the packing case Fig. 1, it is held closed by two or morestaples 0, p, afiixed to other staples s, 6 carried on the bottom a byrods 51, r, a bolt or padlock passing through the rods r, to keep themin place.

For returning the packing case empty a band is passed through the holesin the staples holding the folded sides between the bottom and the lid(Fig. 2

The door 6 is provided with a similar staple combining with the staplesp to ensure its closing.

The sections forming the sides and the lid may be of solid metal or anyother material or formed of a skeleton frame with a solid or openworkcovering or provided with wire netting, as shown in the drawing, whenthese cases are to be used for the transport of living animals, such asfowls, carrier pigeons or the like.
